A capacitor is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known capacitor manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded ...
That increases the capacitance value, depending on the rated voltage, by a factor of up to 200 for non-solid aluminium electrolytic capacitors as well as for solid tantalum electrolytic capacitors. [5] [6] [7] The large surface compared to a smooth one is the second reason for the relatively high capacitance values of electrolytic capacitors ...
Sprague Electric continued to make capacitor and resistive components to meet military requirements of quality and reliability. Robert C. Sprague was also a member of War Production Board for the Advisory Committee on Capacitors (1942-1945). Tantalum vs aluminum oxide electrolytic capacitors. Size comparison of two equal value capacitors.
Typical application circuit for a simple mains PSU, showing transformer, bridge rectifier, 78xx regulator and filter capacitors. Electrolytic capacitors are usually used due to high capacity at low cost and low size. Smaller non-electrolytics may be paralleled with these to compensate for electrolytics' poor performance at high frequencies.
Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.
This oxide layer has a voltage proof of approximately 1 to 1.5 V. [37] Therefore, aluminum electrolytic capacitors with non-solid electrolyte can continuously withstand a very small reverse voltage [38] and, for example, can be measured with an AC voltage of about 0.5 V, as specified in relevant standards.
